Low hydraulic head hydropower coagulation process method

Abstract

The present invention provides a low hydraulic head hydropower coagulation process method, which mainly comprises that: a linear spraying perforated pipe is arranged above a water inlet to spray an agent, effects of diversion, mixing and spiral flow generation of an L-shaped hydropower hybrid spiral flow generator are adopted, and concurrently a contact flocculation effect of a suspension active sludge layer is adopted to achieve an integrated hydropower coagulation process of the low hydraulic head. Compared with the conventional coagulation method, the low hydraulic head hydropower coagulation process method of the present invention has the following characteristics that: coagulation efficiency is high, flocculation and water distribution of the suspension active sludge layer are balanced, an agent addition amount is small, the conventional water level height difference of the water treatment process is comprehensively utilized, electricity consumption is not generated, no movement part exists, operation is reliable, and the low hydraulic head hydropower coagulation process method is a coagulation process method with characteristics of high efficiency, energy saving and simpleness.

Description

technical field [0001] The present invention relates to a low water head hydraulic coagulation process, in particular, the full mixing and efficient flocculation of medicament and water are realized by using the diversion, hydraulic mixing, hydraulic spinning and contact flocculation of L-shaped hydraulic mixing spinner an integrated approach. Background technique [0002] In the field of water treatment, coagulation-sedimentation is one of the most basic water treatment methods or processes. In the tap water industry, coagulation-sedimentation-filtration-disinfection is the most conventional treatment method, and so far most of the world's surface water plants use this method to produce tap water; in the advanced sewage treatment process, coagulation-sedimentation It is one of the commonly used methods; in industrial wastewater treatment, coagulation-sedimentation is an important technical means. In order to realize the coagulation process, the agent and water should be m...

[0003] Utility model patent application "An Integrated Water Purifier" (notification number CN 2512772Y, announcement date 2002.9.25), the mixing and flocculation of the device is completed by a mixer and a three-stage vortex sleeve, but this method requires a special mixer and It needs electricity and maintenance workload. At the same time, the flocculation time of this method is short, the flocculation effect is average, and the effective utilization rate of the circular inclined tube is low, and the height is limited by engineering applications. Therefore, this method is difficult to scale up to a larger scale and difficult to Successfully applied to the sedimentation of inclined tubes in large-area rectangular pools

However, in the current relatively large-scale AO diatomite sewage treatment process, a large-scale hydraulic circulation clarifier is used, and the dosing and mixing of the hydraulic circulation clarification tank is mixed by a water pump impeller, which consumes a lot of energy and requires special equipment. pumping equipment and pump rooms

[0004] Invention patent application "Integrated device, system and process for biochemical treatment of sewage" (publication number CN 102923908A, publication date 2013.2.13), the water flow in the device is mixed with falling water after adding the chemical agent in the chemical spray perforated pipe , the mixing intensity is not sufficient, and the degree of contact and collision between the floc particles in the water body below the sedimentation component in the device is insufficient. To achieve qualified effluent quality, a relatively large amount of chemicals needs to be added. In addition, the device is large-scale The effect of water distribution becomes worse after enlargement, so there is room for further improvement of the mixing and flocculation effect of the device
